linux安装cgdb

下载完cgdb之后&＃xff0c;进入cgdb目录&＃xff0c;执行&＃xff1a;

$ ./configure --prefix&＃61;/usr/local
$ make
$ sudo make install

在第一步出现如下错误&＃xff0c;则按下面方法解决&＃xff1a;

出现错误&＃xff1a;
configure: error: CGDB requires curses.h or ncurses/curses.h to build.
解决方案&＃xff1a;
yum install ncurses-devel


出现错误&＃xff1a;
configure: error: Please install makeinfo before installing
解决方案&＃xff1a;
yum install texinfo

如果是 CentOS 8.0 及以上系统&＃xff0c;需要先执行&＃xff1a;

yum config-manager --set-enabled PowerTools 


出现错误&＃xff1a;
configure: error: Please install help2man
解决方案&＃xff1a;
yum install help2man


出现错误&＃xff1a;
configure: error: CGDB requires GNU readline 5.1 or greater to link.
  If you used --with-readline instead of using the system readline library,
  make sure to set the correct readline library on the linker search path
  via LD_LIBRARY_PATH or some other facility.
解决方案&＃xff1a;
yum install readline-devel


出现错误&＃xff1a;
configure: error: Please install flex before installing
解决方案&＃xff1a;
yum install flex

安装好了以后&＃xff0c;输入"cgdb 要调试的程序名“即可以进行调试&＃xff0c;比如我这里调试mysql源码&＃xff1a;

zhangyl 2016.11.30日补充&＃xff1a;

cgdb不足之处&＃xff1a;
cgdb中调用gdb的print命令无法显示字符串类型中的中文字符&＃xff0c;要么显示乱码&＃xff0c;要么不显示&＃xff0c;这给程序调试带来了很大的困扰。
这点需要注意&＃xff01;&＃xff01;&＃xff01;
